Not directly, but you can always delegate the calls to a singleton
instance. However, this is not recommended. If you need state,
use ASP.NET's state management. ASP.NET's state can be configured
to be cluster-able, restartable, etc. None of those can be
accomplished with a singleton instance (w/out a lot of work).
